Product Description

Product Overview

NKI Type Combined Needle Roller Bearings are engineered to optimize space utilization in rolling bearing applications, delivering reliable performance under radial heavy loads or axial light loads.

These precision bearings feature needle rollers that handle radial loads, with axial load capacity limited to 25% of the radial load. For bidirectional axial force applications, two needle-angular contact ball bearings can be installed in close proximity to provide mutual support.
